Winding coupling phase for pseudo-spin-derived topological photonics
Topology has brought novel physics perspectives and manipulation methods to optical research, with its hallmark achievement being the ability to enable unidirectional (reflectionless) and robust (highly tolerant to perturbations) transmission of light. Within this research domain, pseudo-spin-derived topological photonic crystals can achieve unidirectional, robust transmission of optical modes ...

MOREWestlake University Team Develops Ice-Assisted van der Waals Metal Contact Technology, Breaking Through Perovskite Device Interface Challenges
Recently, the research group led by Professor Min Qiu from School of Engineering, Westlake University developed a novel ice-assisted van der Waals metal contact technology, addressing a major challenge in perosvkite-electrode interface of halide perovskite devices. Due to the "soft lattice" nature of perovskites, traditional electrode fabrication processes easily introduce defects at the peros...
MORELight-Controlled Mechanical Oscillator Utilizing the Van der Waals Force
At the microscale, surface forces between objects far exceed volume forces like gravity, making contact adhesion highly likely: two closely positioned objects become difficult to separate due to surface forces. For dry, uncharged surfaces, the van der Waals force is typically the dominant surface force. Because the Van der Waals force hinders and restricts movement, researchers designing mechan...
MORE3.8g, mass producible SiC diffractive waveguide without Rainbow Artifacts
Since its inception, augmented reality (AR) technology has faced a persistent engineering challenge: achieving a wide field of view (FOV) and excellent display quality within a compact and lightweight form factor. Diffractive waveguide technology is recognized as the mainstream solution for AR displays due to its optimal balance of a thin profile, wide FOV, and mass production potential. Howeve...
